For positive choke valve, special tools are adopted to replace oil nozzle. In this way, flow section can be controlled to control flow fluid. Choke oil nozzle is manufactured with ceramic or cemented carbide, which is characterized as wearing resistance and erosion resistance, which is convenient to replace with special tool. Valve body and valve bonnet are connected with union,which make it easy to replace oil nozzle.
The throttle valve can be divided into an adjustable throttle valve and a fixed throttle valve according to the structure, and the fixed throttle body and the adjustable flow valve body can be interchanged. According to the principle of operation, it is divided into manual throttle valve and hydraulic throttle valve. The bonnet and valve body are metal and metal sealed. Among them, the fixed throttle valve nozzle, the adjustable throttle valve stem, the valve core and the valve seat are all made of hard alloy, which has the characteristics of wear resistance, erosion resistance and reliable operation. According to the function, it can be divided into a needle-shaped adjustable flow valve and a cylindrical adjustable flow valve. The needle-shaped adjustable flow valve is mainly used for oil (gas) wellhead device for oil (gas) adjustment; the tubular adjustable flow valve is mainly used for throttling and killing manifold, and for controlling fluid pressure in the well.
